Title: Axial structure of the nucleon on large-volume lattice QCD at the physical point
Abstract: The nucleon form factors are very good probes to investigate the nucleon structure. Although great theoretical and experimental efforts for the form factors have been devoted to improving our knowledge of the nucleon structure, there are several unsolved problems and tensions associated with the fundamental properties of nucleons such as the proton radius puzzle and high-precision determination of the neutrino-nucleon scattering.
In this talk, I present our resent results about the nucleon axial, induced pseudoscalar, and pseudoscalar form factors.
Based on our simulation, we also investigate the partially conserved axial-vector (PCAC) relation and the low-energy relations arising from PCAC relation by using lattice QCD data, which offers a theoretical insight into the pion-pole dominance model.
